Google has built a tool to help with k8s development: https://github.com/GoogleContainerTools/skaffold. It suggests ways to store information for reuse by team mates/CI/etc.
There is also a Terraform Kubernetes provider, which allows you to keep your whole Kubernetes configuration as Terraform config files: https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs. If you already use Terraform or other Hashicorp tools, this may be a good option.
